Abstract
An umbrella having a simplified construction which dispenses with the stretcher members of conventional umbrellas and has one end hinged to the central portion of each rib. Said umbrella includes a runner (4) axially slidable along the umbrella pole (1) between a folded position in which the ribs (3, 3') can be folded against the pole, and an unfurled position in which the runner engages the ribs and holds them in the extended position. For this purpose, the runner comprises an upper frusto-conical portion (46) engageable with the ends (35) of the reinforcing portions (31) of the ribs.
Claims18
An umbrella comprising a rod, one end of which serves as a handle, while the other end forms a mount on which are hinged radial ribs, and a slide block mounted on an axial slideway along the length of the rod, between an opening position in which it comes to a stop against the said ribs, maintaining them in a deployed position, and a closed position in which the ribs can fold in against the rod, wherein the slide block comprises an upper part, featuring an outer surface with a diameter which tapers towards the top, shaped to cooperate with a projecting shaping of each of the ribs, so as to maintain the ribs in the deployed position when the slide block is maintained in the open position, said projecting shaping of each of the ribs comprising to that effect a contact surface with a substantially straight generatrix, oriented so as to be in a position substantially parallel to the outer surface of the slide block when the ribs are in the deployed position.
